Formed in the summer, the group’s Facebook page has more than 430 likes, and they intend to stage vigils outside the Eye-based firm once a month.

Organiser Tom Fenner, from Bury St Edmunds, said the group is peaceful and believes in total animal liberation.

“We ask drivers to stop for three minutes, we will bear witness to the animals, give them a bit of compassion, a bit of love, speak to them, give them some water, and also capture their plight as well, so other people can see what they have to go through, even in the transportation process,” he said. “Obviously if they are not prepared to stop we will try to work with them, but we will passively stop the trucks, we will stand in the road and stop them.

“It’s a no-hate approach. It’s peaceful, and there is no hate towards the drivers. We don’t want to stop them from earning a living, it’s not what we are asking. We just want them to stop for three minutes.

Speaking personally I don’t care how nicely you want to kill someone. If they don’t want to die, it is still murder

“C and K Meats have been targeted because they are local and they slaughter animals. They haven’t been found to do anything specifically more cruel than anywhere else other than the slaughter of the innocent.

“Speaking personally I don’t care how nicely you want to kill someone. If they don’t want to die, it is still murder.”

Kevin Burrows, managing director of C and K Meats, said people were free to voice their opinions but expressed concern about people trying to stop lorries from entering the site.

He added it was the first event “of this scale” at the premises, and had told drivers not to allow anyone to give water to pigs over fears of contamination.
